When I 'Create or Update PI Point' I get the message, "Failed to create or update the data reference for Attribute '**' in Element '**' in Element '**': The attribute's template data reference is not configured for tag creation.Configuration creation or update completed with 1 errors."

I checked the value types and Data references and everything seems to be in order.

I didn't quite understand the origin of the error in your case, but if you want to create that PI Point, here is what you need to do to resolve this error:

Go to the element template, click on the attribute and choose "Settings...". The PI Point Data Reference window will open. There you can choose to enable tag creation. It will typically define the Point Type to Float64, but you may change this and also define other parameters by clicking on the "..." button. The "Tag name" field defines the tag naming pattern. After everything is correctly set up, check-in the changes.

Thanks for the answer. I had already done as you suggested yesterday, and the same error persisted (I must have miscommunicated this in my original question), I am wondering what could be the root cause of the error (eg. path error, accessing the wrong database, perhaps a wrong type of PI Point, etc...)?

I think now I understand what happened. You manually created an event frame, then you went to its Attributes and you saw the error. In this case, instead of doing the procedure that I described on the Element Template, you would need to do it on the Event Frame Template.

But in the context of this exercise, you don't need to create a PI Point, you just need to reference the PI Point that is configured on the Element by using what we call Retrieval Methods. By using the retrieval methods, the Event Frame attribute queries the PI Point Attribute configure on the referenced Element.
